Law of Physics broken!!
No, it isn’t any of the laws of thermodynamics – a group in Bristol has broken the “Wiedemann-Franz Law”. This law states that the ratio of the electronic contribution – how much is contributed by the electrons – to the thermal conductivity and the electrical conductivity of a metal is proportional to the temperature. The original article ishere.
A potential application of this, going by the Physorg article and the comments on it, is as an insulator OR in transporting heat – i.e. as a heat sink – especially with more heat-intensive machinery such as supercomputers. I have no idea, however, when this will happen.
